A wideband Artificial Magnetic Conductor Yagi antenna for 60-GHz standard 0.13-µm CMOS applications

This paper presents a low-cost wideband 60-GHz on-chip Artificial Magnetic Conductor (AMC) Yagi antenna utilizing a standard 0.13-μm CMOS process. The stand-alone Yagi antenna is designed based on a four-element topology in coplanar waveguide (CPW), using the top thick metal and metal layer M2. Furthermore, by designing and integrating an optimized AMC plane, which has a very wide fractional bandwidth of 31%, the radiation efficiency of this novel AMC Yagi antenna is significantly improved by more than 90% compared to a common Yagi antenna without AMC. The simulation results in HFSS also indicate that the impedance bandwidth (S₁₁<;-10 dB) covers 53.5 GHz to 69 GHz, while an excellent peak power gain of -0.2 dBi is obtained. The proposed antenna occupies an area of 2.2 × 1.3 mm².
